DURAN® Flask, Kjeldahl
DURAN® Flask, Kjeldahl
DURAN® Kjeldahl flasks are subjected to extreme chemical and physical stresses. Therefore, the wall thickness should not be too thick to avoid overheating, which can lead to breakage due to remaining (permanent) stresses, on the one hand, and not too thin due to the noticeable glass removal in the alkaline medium, on the other hand. In order to offer the user the safest possible compromise while taking the technological conditions into account, the wall thickness of the DURAN® Kjeldahl flasks in the body are 1-2 mm.

Abdominal vessels are called flasks in the laboratory and, in addition to beakers, are other universally applicable vessels. They are used e.g. for distillation or for heating liquids. Flasks are available in various designs: narrow and wide neck, with or without ground joint, as round or flat bottom flask. Depending on the application, the required flask with its specific components is selected.
